I wrote python code to process the title.basics.tsv, name.basics.tsv, and title.principles.tsv files from the IMDb (internet movie database) These files can be found at http://www.imdb.com/interfaces/ I wrote python code to print the primary movie titles and names of the principal cast for 20 films (not television shows) chosen at random. My code ensures there are no adult titles in the list. Fields are separated by tab characters, and one record per line. I have the results written to a file named titles.txt

Here is that working python code:

import random # open files  open('name.basics1.tsv', encoding="utf8") moviesfile = open('title.basics1.tsv', encoding="utf8") #counts the total number of lines contained in the specific file def lineCount(fileObject): counter = 0 line = " "  while not line == "": counter += 1 line = fileObject.readline() fileObject.seek(0) return counter # gets data off a specific line of a specific file def getDataOfLine(fileObject, lineNum): counter = 0 line = " "  while not counter == lineNum: counter += 1 line = fileObject.readline() fileObject.seek(0) return line # main function - starts by opening the moviesfile, counting the total number of lines in the file, # and creating an empty array for movies. While the "movies" array is less than 20, # the function will randomly select a line, get the data off that line, and make sure # currMovie is a movie (not a short or TvEpisode) and that it is NOT an adult movie. # If it satisfies these constraints, we will append currMovie data to the movies array.  def main(): moviesfile = open("title.basics1.tsv", encoding="utf8") totalLines = lineCount(moviesfile) movies = [] while not len(movies) == 20: lineNumber = int(random.uniform(1, totalLines)) currMovie = getDataOfLine(moviesfile, lineNumber).split("\t") if currMovie[1] == "movie" and currMovie[4] == "0": movies.append(currMovie) moviesfile.close() # opens the principal cast file  # it then reads the data by lines, splitting them at the tabs,  # and then for currMovie in the array of movies, sees if the  # tconst of title.basics1.tsv file matches the tconst of title.principals1.tsv file  # If they do, we split them with commas and append appropriate tconst id to currMovie   principalCastFile = open("title.principals1.tsv", encoding="utf8") line = " "  while not line == "": line = principalCastFile.readline()[:-1] lineSplit = line.split("\t") for currMovie in movies: if currMovie[0] == lineSplit[0]: currMovie.append(lineSplit[1].split(",")) principalCastFile.close() # opens the castFile and reads the data for the cast, splits info at tabs, and appends each  # of the cast to the appropriate currMovie of the movies array   castFile = open("name.basics1.tsv", encoding="utf8") line = " "  while not line == "": line = castFile.readline() lineSplit = line.split("\t") for currMovie in movies: for cast in currMovie[-1]: if lineSplit[0] == cast: currMovie[-1].append(lineSplit[1]) currMovie[-1].remove(lineSplit[0]) castFile.close() # writes 20 random movies titles (that are not adult movies) along with the principalCast to the titles.txt document   titleAndCastFile = open("titles.txt", 'w') string = ""  for currMovie in movies: string += currMovie[2] for cast in currMovie[-1]: string += "\t" + cast string += " "  titleAndCastFile.write(string) titleAndCastFile.close() # runs main function main() 

I need help adding to my code to write to a second file called actress.txt that lists the complete records of all actresses that appear in my random 20 movie sample from part one. I am supposed to separate the actress records with 20 equal signs. The actress records are located in a very large file (over 7 milllion lines) called actresses.list

I am providing the first several hundred lines of the actresses.list so you know what format this file is in...The code should be able to be written without actually having access to this file.

RULES: 1 Movies and recurring TV roles only, no guest appearances 2 Please submit entries in the format outlined at the end of the list 3 Feel free to submit new actresses

"xxxxx" = a television series "xxxxx" (mini) = a television mini-series [xxxxx] = character name = number to indicate billing position in credits (TV) = TV movie, or made for cable movie (V) = made for video movie (this category does NOT include TV episodes repackaged for video, guest appearances in variety/comedy specials released on video, or self-help/physical fitness videos)
